Sealing means for perforated container caps



Patented 'Man 4, 1,930 y crimson H. GLITZKE, or KANSAS oirY, Missouar YSELLING MEANS non rnnronn'rnn ooNrAINER CAPs Application led February27, 1928. Serial No. 257,310.

The present invention relates to closure constructions for receptacles,such as cans,

bottles, jars and the like, and particularly 'to containers from whichthe contents are designed to be discharged by shaking the container andallowing the contents to escape by j Y way .of openings orperforationsthe cap or closureelement.

` The principal' object in view-is to provide provided in a closure capor element of this character having the usual spraying or siftingopenings' or perforations, together with means for j Y ftemporarilysealing such openings or perfovthe contents thereof.

rations until suchtimeas it is desired to use ywith this Object in View,i provide liner 4disk or diaphragmy within the capor closure element, inposition to seal the openings or perforations thereof, Said liner ordiaphragm element .being of suitable irangible material in order'thatthe same may be readily punc- V turedi'or allowing the contents of theconl tainer to be ejectedthrough the spraying or l siftingjopenings inthe cap or closure element.-v h y In carrying out the invention 1npractice, I 'provide a secondjperforated disk adapted to t inside thecap or"closure element with its-openings in register with the openingsin 3o.

they cap element and acting to hold the liner vor diaphragm element insnug fitting relation against the inner yface of the cap;

lVViththe foregoing objects. inview,the 1nvention will now be describedby reference to the accompanying drawing illustrating a suitable andpractical form of construction :tor embodying the proposed improvement,

lafter which the features deemed to be novely will be set forth andclaimed,

y 'In the drawing.:-

Figure l is a perspective view showing a container provided with a capor closure element equipped with the present improvevview of said cap orclosure element, and ilment; and y n y `Figure 2 k1s a transverse detailsectlonal lustrating the interior construction comprisf ing theyimprovement. f

Referring now to said drawing in detail,

y this shows-the invention embodied in a closure or cap element 3 ofcommon construction having the marginal iange portion 4 for embracingthe neck portion of a container, which may be a bottle, can, or anyother desiredform of receptacle such as a jar having any suitable formof thread or other expedient (not'shown) adapted for retainingengagement with marginal inturned portions 6 'provided on the fiang'e 4of the cap; such reed to fit snugly within the iange portion l p andagainst the interior face of the body portion thereof and hence insealingrelation to the openings 7, as clearly shown in Figure 2. Thisdisk or diaphragmv element 8 is of suitable frangible material, adaptedto be read- --ily punctured by means of a suitable pointed instrument'f)as represented in Figure 2. For tacilltating such punching operation, aswell as forassisting in maintaining the diaphragm or disk 8 in theposition illustrated, that is, in sealing relation to the'openings orperforations 7, a second disk orwafer 10 is provided of substantiallythe same size as the disk or diaphragm 8 and fitting snugly against thelatter within the flange 4, this second disk 10 being also provided withone or more openings 12, corresponding to the openings 7 and inposition. to accurately register with said openings 7 as shown in Figure2. By this means, it is apparent that by use of the tool or instrument9, little effort is required for effecting the punching of the portionsof the disk or diaphragm 8 which are embraced be- 90 tween theregistering openings 7 and l2 and a more effective punching action isproduced due to the cooperating openings in registered relation. In thisway, the openings 7 are unsealed, and the contents of the jar or can D5may be sprayed or sifted out through said openings 7 in the usual way.The improvement thus provides a very simple and yet inexpensive andeliicient means for the temporary sealing of perforated caps 109 3 anduntil such time as their use is desired, and While I have illustrated inthe drawing n `the use of a plurality of the perforations 7 `it isapparent that this number is unessential, and the cap 3 may be providedwith but one such opening, or as many as may be desired; it being onlyynecessary that the interior disk 10 vbe provided with onel ormoreopenings in such position as to register the l lo same with the outeropenings 7 of the cap.

Y While I have illustrated and" described what I now regard as thepreferred form of embodying the improvement, I desire to re# i serve theright tol make such changes and? modifications as may fairly fall withinthe scope of the appended claims. f v f Having thus described myinvention, what I claim and desire to secure by Letters Patent is f 1. Acap structure for containers comprisf ing a perforated capelementadaptedto be removably fitted to the container, a perfo rateddisk secured inside the cap and .having perforations of the same sizeasthe perfora tions of said cap element and in yregistered relationtherewith, and a closure elementcomprising an imperforate disk ordiaphragm of frangible material embraced between said first diskV andcap element and sealing the perforations thereof.

2.` A container top provided withfone or more perforations, a disklocated inside said Vtop and provided with one or` more perforations ofthe same size asthe perforations of the top and registering therewith,and a closure velement comprising an imperforate disk V or'diaphragm offrangible material retained in place between said rst disk and the inside of the top for temporarily sealing vtheA n 40 perforations thereof.Y

In witness whereof I hereunto affix my signature, s
